Int. Cl. BOSd 1/00 11.8. CH. 4-145 22 Claims ABSTRACT 0F THE DESCLGSURE A plumbing fixture which facilitates provision of a hand-held spray unit in a bathtub or shower installation. It comprises a casing which incorporates a diverter valve assembly and an ornamental housing which conceals the casing and is adapted to function as a tub spout or as a shower head support.

This application is a continuation-in-part of my copending patent application, Ser. No. 392,202, filed Aug. 26, 1964, for Plumbing Fixture for Baths, now abandoned. 1

This invention relates to a hand-operated bath installation and more particularly to provision of a moveable spray in a shower or bathtub installation.

The primary object of the present invention is to provide new and improved means for embodying a hand spray unit in a bath. As used herein, the term bath is intended to apply to separate tub and shower installations as well as combined tub shower installations.

Another primary object is to provide a new and improved plumbing fixture which is adapted to be attached diverting the flow of water from the shower head to tub spout without need for any dismembering of a building partition and which also incorporates a diverter valve for diverting the flow of water from the shower head to tub spout to a hand operated moveable spray unit.

A more specific object is to provide a new and improved diverter valve assembly which can be used to combine a hand held spray unit with a bathtub spout or a wall mounted shower head.

Another specific object of the invention is to provide a plumbing fixture comprising a diverter valve assembly and an ornamental housing therefor which facilitates provisions of a handheld spray unit in a bathtub or shower installation, the diverter valve assembly being adapted for use in new or existing installations and the housing designed to conceal the valve assembly and function as a tub spout or a support for a shower head.

A further object is to provide a new and patentable improvement over the prior art. such as the apparatus illustrated and described in U.S. Patent No. 2,867,230, issued I an. 6, 1959, to R. E. Bletcher et al. for Diverter Valve fora Shower Installation.

For a fuller understanding of the nature and objects of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings wherein:

FIG. 1 is a front view in elevation of wall shower installation embodying the present invention;

FIG. 2 is a side view of the apparatus of FIG. 1;

FIG. 3 is an enlarged sectional view of the top portion of the apparatus of FIG. 2;

FIG. 4 is an enlarged sectional view similar to FIG. 3 of an alternate form of the invention;

FIG. 5 is an enlarged sectional view similar in part to FIG. 4 of still another embodiment of the invention; and

FIG. 6 is an enlarged view of a portion of FIG. 5.

Turning first to FIGS. 1 and 2, there is shown a typical bath shower installation embodyin the present invention. The installation comprises a mixing valve 2 mounted in a wall 4 and connected to a pair of pipes 8 and 10 which supply hot and cold water. Valve 2 is of conventional construction, 'having a rotatable operating handle 12 which is used to select the desired mixed water temperature. Preferably, but not necessarily, valve 2 may be constructed in accordance with the teachings of my US. Patents Nos. 2,308,127, issued Jan. 12, 1943, and 3,099,996, issued Aug. 6, 1963 respectively. The mixed Water output of valve 2 is discharged into a mixed water supply pipe 14 which extends up behind or within wall 4. The upper end of pipe 14 is fitted with an elbow 16 to which is connected a nipple 18. The latter extends through wall 4 and projects beyond its front surface a suitable distance e.g., 1 inch, for connection to a novel plumbing fixture identified generally at 20 constructed in accordance with the present invention. This plumbing fixture is connected to and supports a swivel mounted shower head 22 and a hand-spray assembly comprising a spray outlet hose 24 and a handoperated spray unit 26. The latter is of conventional construction comprising a normally closed valve (not shown) which is opened by pressing its operating handle 28, and also a spray head 30. A hanger in the form of a bracket 32 attached to wall 4 is provided to support spray unit 26 when not in use.

Turning now to FIG. 3, the new and improved plumbing fixture 20 includes a diverter valve assembly which comprises a hollow valve casing 34 having an inlet end 36, an outlet end 38, and a side outlet 40. Casing 34 is internally threaded at its inlet end 36 so as to screw into nipple 18. On its inside casing 34 is provided with a generally transversely-extending partition 44 which separates the outlet end 38 from the inlet end 36 and the side outlet 40. Partition 44 includes a longitudinally-extending portion 46 whose plane is parallel to the longitudinal axis of the valve casing and is at right angles to the center axis of side outlet 40. This portion 46 is provided with a hole 48 which provides communication between outlet end 38 on the one hand and inlet end 36 and side outlet on the other hand.

The side outlet 40 is internally threaded to receive a hollow openended sleeve 50 which extends into the valve casing a distance suflicient for its inner or upper end to engage the longitudinallyextending portion 46 of partition 44 in coaxial relation with hole 43. It is to be observed that the discharge opening at the upper end of sleeve 50 is smaller than hole 48. To provide a good seal between the end of sleeve 50 and partition 44, the longitudinally-extending portion 46 is provided with a counterbore for hole 48 large enough to seat the end of the sleeve and also an intervening washer 54. An O-ring 56 helps assure a good seal between sleeve 50 and the surrounding wall which defines side outlet 40. A plurality of small ports 58 permit to flow from the inlet end of casing 34 into sleeve 50. water to flow from the inlet end of casing 34 into sleeve 50. is determined by a valve member mounted within the sleeve. The valve member consists of a valve stem 60 having a valve head 62 at its upper end and a piston 64 at its lower end. Valve head 62 is adapted to seat on the upper end of sleeve 50 so as to close oti flow of water to end outlet 38. The side wall of valve casing 34 is fitted with a cavity 66 Which slidably accommodates and guides the upper end of valve head 62 so the latter may reciprocate axially and also rotate but may not shift laterally. A passageway 68 in stem 60 and valve head 62 functions to allow water to bleed into cavity 66 so as to damp upward movements of the valve head. Piston 64 is larger in diameter than valve head 62 and thereby has a larger effective surface area exposed to water pressure. This is essential in order to have the valve member assume the position 3 shown in FIG. 3 (where valve head 62 is seated on the end of sleeve 50 to close off the flow of water to outlet end 38) when the hand spray unit is operated.

Operation of the valve member is straightforward. When the hand spray unit 26 is closed it presents a high resistance to flow which appears as a back pressure in hose 24 which is substantially greater than any corresponding back pressure in the outlet end 38 of casing 34 (shower head 22 offers a resistance to flow which is less than that presented by spray unit 26 when the latter is closed and greater than spray unit 26 when the latter is fully open). Accordingly, the net force applied to the valve member will be upward, so that valve head 62 will be held in open position relative to sleeve 50 and water will flow to the shower head via outlet end 38. However, when hand spray unit 26 is actuated, the resulting drop in back pressure in hose 24 will produce a change in the eifective pressure load on position 64, causing the net force exerted 'on the valve member to change direction. When this occurs, valve head 62 will seat on sleeve 50, terminating fiow to shower head 22. No water will flow out of the shower head so long as the hand spray unit is passing water. However, when the hand spray unit is shut off, valve head 62 will move off of its seat and flow to the shower head will be resumed almost instantaneously.

Also forming part of the new and improved plumbing *fixture 20 is a housing 70 which serves two purposes. First of all it provides an ornamental cover or shell for valve casing 34. Secondly, it functions to support the shower head 22 and to provide a -fluid fiow connection between the shower head and valve casing 34. Housing 70 is open at its rear end to fit over the valve casing and is provided with a internal wall portion 72 that subdivides it into a rear chamber 74 that accommodates valve casing 34 and a front flow chamber 76 through which water flows to the shower head. The wall portion 72 has an internally threaded hole 78 whereby the housing is screwed onto the valve casing. The front end of the housing is provided with an internally threaded hole 80 which functions as a discharge port for flow chamber 76. The shower head includes a conventional ball-socket connection 82 and a sleeve 84 which screws into hole 80. Housing 70 also has a hole 86 on its bottom side through which sleeve 50 protrudes just enough to make a threaded connection with flexible hose 24. In practice sleeve 50 and housing 70 are plated to yield a polished, rust resistant surface, as is usual with shower heads and other bath fixtures.

The foregoing construction is easy to install in existing shower baths. In practice valve casing 34, sleeve 50 and housing 70 are preassembled as one unit and then are mounted in place by screwing the inlet end of the valve casing onto nipple 18. The unit is screwed on far enough tor the rear end of the housing to engage the wall 4. Thereafter, the shower head and the hand spray unit are attached in the manner described and illustrated. The completed installation is attractive in appearance as well as satisfactory in operation and economical in cost.

A "further advantage of the invention is that it is applicable to bathtub spouts as well as to shower heads, as shown in FIG. 4 where like numbers refer to like parts of the embodiment of FIG. 3. The same diverter valve assembly without change may be used for tub spout and shower head installations. However, as illustrated in FIG. 4, it is preferred that the diverter valve casing 34A be made somewhat longer at its outlet end 38A so that the point of discharge is further -from the supporting wall 4 than is the case with the apparatus of FIG. 3. In the case of the tub spout installation, the diverted valve housing 70A is constructed to function as a tub spout. In this connection, it is to be observed that housing 70A has the same general construction as the housing 70 employed for shower head installation, comprising an internal wall portion 72A that subdivides it into a rear chamber 74A that accommodates valve casing 34A and a front llow chamber 76A through which water is discharged downwardly in the bathtub via a discharge port 80A. The wall portion 72A has an internally threaded hole 78A so that the housing can be screwed onto valve casing 34A. Housing 70A also has a hole 86A on its bottom side for sleeve 50 of the diverter valve assembly. Like the embodiment of FIG. 3, housing 70A and the associated diverter valve can be installed or removed as a complete assembly. On the other hand, removal of the reciprocal diverter valve member for inspection or repair can be achieved by unscrewing sleeve 50A from valve casing 34A without unscrewing the whole fixture from water supply pipe 18A.

Where it is desired that the shorter diverter valve assembly of FIG. *3 be useable tor tub spout as well as shower head installations, the tub spout type housing 70A may be made with its internal wall portion 72A extending -further back so as to be engageable with the threaded end 38 of valve casing 34. Alternatively housing 70A may be made shorter so that its internal wall portion 72A can be screwed onto diverter valve casing 34 a suflicient amount before the rear end of the housing engages the supporting wall 4.

Of course, in the case of a bathtub installation, the supporting bracket 32 'for the hand spray unit 26 is mounted at a point convenient to the bather, preferably slightly above and to one side of the spout-shaped housing 70A.

FIGS. 5 and 6 illustrate another modification of the invention that is designed to prevent backflow of water into the supply line from a bathtub. Although it rarely occurs, it is possible due to a sudden high water demand elsewhere, e.g., when a fire department connects one or more high pressure pumping units to a water main, for a negative pressure to be created in a domestic water 'supply line. If at the time this negative pressure condition exists the hand spray unit 26 is opened below the surface of a pool of bath water, the negative pressure may suck the bath water -far enough back into the supply line to contaminate the water supply. This type of siphoning action is obviated by the embodiment of FIGS. 5 and 6. This alternative form of the invention comprises a d-iverter valve casing 90 having an inlet end 92, an outlet end 94, and a side outlet 96. The inlet end 92 is internally threaded so as to screw into a nipple (shown in phantom at 98) that connects to a mixed water supply pipe located behind a wall 100.

The interior of valve casing 90 is provided with a transversely extending partition 102 which separates the outlet end 94 'from the inlet end 92 and the side outlet 96. Partition 102 includes a longitudinally extending portion 104 whose plane is parallel to the longitudinal axis of the valve casing and is at right angles to the center axis of side outlet 96. This portion 104 is provided with a hole 106 which provides communication between outlet end 94 on the one hand and inlet end 92 and side outlet 96 on the other hand. Hole 106 is counterbored so as to provide a valve seat 107.

Also formed integral with the valve casing is an interior partition 108 that joins with partition 102 and surrounds side outlet 96 so as to define an exit chamber 109. This partition 108 includes a portion 110 that extends parallel to the longitudinal axis of the valve casing and includes a hole 111 that is formed co-axial with side outlet 96 and hole 106. Hole 111 is substantially larger than hole 106.

Mounted within the valve casing is a diverter valve assembly consisting of a valve stem 112 having a first valve head 114 at its lower end and a second larger valve head 116 at its upper end. Preferably valve head 114 is formed integral with valve stem 112. Alternatively valve head 114 may be sweated onto the valve stem or secured thereto by other appropriate means, e.g., by brazing or soldering. Valve head 114 is sized to mate with valve seat 107. The bottom end of valve stem 112 is enlarged as shown at 118. This solid enlargement of stem 112 is slidably position in a cup 120 formed in the underside of the valve casing. The internal diameter of the cup 120 is sized so as to slidably accommodate the enlargement 118 of the valve stem. The clearance between cup 120 and the valve stem enlargement 118 is sufficiently small to keep the valve stem aligned with the axes of holes 106 and 111, but large enough to permit water to flow into and out of the cup as the valve assembly moves upward and downward respectively. The displacement of the water in the cup by valve stem enlargement 118 damps downward movement of the valve assembly.

The larger valve head 116 is small enough to fit within hole 111 but has a peripheral flange 124 sized to engage partition 110 which serves as a valve seat. Valve head 116 is formed as a separate disc and has a center hole sized to accommodate the valve stem 112. The latter has a flange 128 that limits downward movement of the valve head 116. The upper end of the valve stem is threaded to accommodate a nut 130 which serves to clamp valve head 116 against flange 128.

At this point it is believed to be apparent that the valve assembly is adapted to alternately connect the inlet end 92 to outlet end 94 or side outlet 96, with hole 106 permitting passage of water to outlet end 94 when valve head 116 engages its valve seat 110, and hole 111 permitting flow of water to side outlet 96 when valve head 114 engages its valve seat 107.

The side outlet 96 is threaded to receive a bushing 132, which in turn is threaded on its interior to receive a hollow open ended sleeve 134. The outer end of sleeve 134 is threaded as shown at 136 to receive a coupling nut 140 attached to a ferrule 142 that is secured to the end and forms part of a flexible outlet hose (not shown) similar to hose 24 shown in FIGS. 3 and 4. It is to be understood that this hose is provided at its opposite end with a handoperated spray unit similar to spray unit 26 shown in FIG. 1.

The outlet end 94 of the diverter valve casing is threaded as shown at 146 to receive a housing 148 in the form of a tub spout. Housing 148 is essentially the same as housing 70A shown in FIG. 4. On its upper side housing 148 has a hole 150 through which extends sleeve 134.

The foregoing apparatus is assembled as one unit so that installation merely involves screwing the inlet end 92 of the valve casing onto nipple 98. Assembly of the apparatus also is straightforward. First the diverter valve is assembled in the valve casing; then with sleeve 134 removed, housing 148 is screwed onto the valve casing. Thereafter sleeve 134 is screwed to the valve casing and the flexible hose (not shown) is attached by screwing its coupling nut onto sleeve 134. Removal of the diverter valve assembly from the valve casing also is easily accomplished. First sleeve 134 and housing 148 are removed. Then bushing 132 and cup 120 are unscrewed from the valve casing. Thereafter nut 130 is removed to free valve head 116. The latter is removed via side outlet 96 while valve stem 112 with valve head 114 is removed via hole 122.

Operation of this alternative embodiment will now be described. Assume for the purpose of this description that the flexible hose 24 shown in FIG. 4 is connected to sleeve 134 and that the valve in its hand spray unit 26 is closed. With the water supply shut off, gravity causes the diverter valve assembly to be in the position of FIG. 5, in which position hole 111 is closed by valve head 116 and hole 106 is open. If the water supply is now turned on, the valve assembly will remain in its FIG. 5 position and water will flow out of the tub spout via hole 106 and outlet end 94. Water will continue to be discharged in this manner until the valve in hand spray unit 26 is opened, whereupon the drop in pressure on the upper side of valve head 116 will permit the incoming water (if its pressure is suflicient) to move the diverted valve assembly upward to the position shown in FIG. 6, in which position hole 106 is closed off by valve head 114 and hole 111 is open. Reclosing of the valve of hand spray unit 26 changes the pressure balance on the diverter valve assembly, causing the latter to return to its FIG. 5 position. In the event a negative pressure is suddenly created in the water supply line at a time when the hand spray unit is submerged in bath water with its valve open, the resulting upset in pressure balance will cause the diverter valve assembly to shift back to the position of FIG. 5, in which position valve head 116 prevents bath water from flowing back into the water supply line via hole 111 while valve head 114 exposes hole 106 to the outlet end 94. However, since the tub spout is above the maximum bath water level, the only thing that can be sucked into the water supply line via the tub spout is air. It is believed to be apparent that this anti-backflow position of the diverter valve assembly is not disturbed if the valve of hand spray unit 26 recloses while the negative pressure condition still exists. Restoration of a positive water pressure at the inlet end of casing permits the diverter valve to shift to the position of FIG. 6 when the hand spray valve is opened.

The plumbing fixtures provided by the present invention are convenient and very useful accessories which can be easily installed in both new and old dwellings without need for special wall construction or reconstruction. It is to be noted also that the exterior appearance of housings 70, 70A and 148 can be easily modified to embody any one of a variety of pleasing designs.
